Geschrieben November 14, 2014 at 18:0114. Nov 2014 Hi, Another PSU question. I'm hearing an extremely high pitched whistle from the PSU powering my LED strip. Since my LED strip is used in a wall clock, I cannot have *any* sound coming off the setup... Googling for the subject turns up lots of hits, but I was wondering if there's anything easy I can do to this particular TF model to stop the whistling? I don't know enough about electricity/electronics to try different things.. Thx.

But after about 20 minutes the whistle faded away. My project has been running 24/24 for nearly a week now, and the whistle hasn't returned. So maybe the PSU simply needs to warm up a bit?
